Design and evaluation of a versatile and efficient receiver-initiated link layer for low-power wireless
TLDR
We present A-MAC, a receiver-initiated link layer for low-power wireless networks that supports several services under a unified architecture, and does so more efficiently and scalably than prior approaches. Expand
Surviving wi-fi interference in low power ZigBee networks
TLDR
We study the interference patterns between ZigBee and WiFi networks at the bit-level granularity and design BuzzBuzz to mitigate WiFi interference through header and payload redundancy. Expand
A multifaceted approach to understanding the botnet phenomenon
TLDR
The academic community has long acknowledged the existence of malicious botnets, however to date, very little is known about the behavior of these distributed computing platforms. Expand
Reducing web latency: the virtue of gentle aggression
TLDR
We present the design of novel loss recovery mechanisms for TCP that judiciously use redundant transmissions to minimize timeout-driven recovery. Expand
Wireless Sensor Networks for Healthcare
TLDR
We present some representative applications in the healthcare domain and describe the challenges they introduce to wireless sensor networks due to the required level of trustworthiness and the need to ensure privacy and security of medical data. Expand
Connecting low-power and lossy networks to the internet
TLDR
We present the 6LoWPAN and RoLL working groups to specify standards at various layers of the protocol stack with the goal of connecting low-power and lossy networks to the Internet. Expand
TOSThreads: thread-safe and non-invasive preemption in TinyOS
TLDR
We present TOS-Threads, a threads package for TinyOS that combines the ease of a threaded programming model with the efficiency of an event-based kernel. Expand
Koala: Ultra-Low Power Data Retrieval in Wireless Sensor Networks
TLDR
We present Koala, a reliable data retrieval system designed to operate at permille (.1%) duty cycles, essential for long term environmental monitoring networks. Expand
MEDiSN: Medical emergency detection in sensor networks
TLDR
We develop MEDiSN, a wireless sensor network for monitoring patients' physiological data in hospitals and during disaster events. Expand
Wireless Medical Sensor Networks in Emergency Response: Implementation and Pilot Results
TLDR
This project demonstrates the feasibility of using cost- effective, flexible, and scalable sensor networks to address critical bottlenecks of the emergency response process, from disaster scenes, to ambulances, to hospitals. Expand
